Josef Beneš (11 January 1902 in Prachatice – 17 December 1984 in Prague) was a linguist from Czechoslovakia, specialising in anthroponymy and onomastics.
Beneš studied Bohemistics and Germanistics at the Charles University in Prague, ending in 1930.
After World War II he briefly worked at the Ministry of Education, then returned to the teaching.
Since 1933 he published articles about Czech surnames in specialised journals (as Naše řeč or Zpravodaj místopisné komise ČSAV, ZMK).
Beneš belongs, together with Vladimír Šmilauer, Jan Svoboda and Antonín Profous, among founders of Czech anthroponymy and onomastics.
